Those who see only race/ethnicity in politics in Guyana, as others who see tribe and religion in other countries, are not viewing reality comprehensively, objectively and scientifically. They fail to note that the two major ethnic groups in Guyana are not, in class terms, uni-class; that economics, on the one hand, and politics, ideology, culture and institutions, on the other are inter-related...

Accurate chromosome segregation during mitosis is achieved by the kinetochore fibers (K-fibers) of the spindle apparatus. These fibers are bundles of microtubules (MTs) connected by non-motor bridges. We recently identified a TACC3/ch-TOG/clathrin complex that constitutes the shortest class of inter-MT bridge in K-fibers. TACC3 anchors the complex to MTs and this is dependent on phosphorylation...

is paper reports on the prevalence of traumatic bone lesions among Bronze and Iron Age populations in Armenia. A total of 51 traumatic injuries were observed in a sample of 147 individuals from 8 sites. Injuries were present in 37 males (46.3%, n=80), 13 females (28.9%, n=45), and 1 child (5%, n=20). In four sites (N. Getashen, Noraduz, Shirakavan and Lori Berd) the most affected age class was...

This paper examines session variability modelling for face authentication using Gaussian mixture models. Session variability modelling aims to explicitly model and suppress detrimental within-class (inter-session) variation. We examine two techniques to do this, inter-session variability modelling (ISV) and joint factor analysis (JFA), which were initially developed for speaker authentication. ...

OBJECTIVE The objective of this study was to evaluate the intra-examiner and inter-examiner reproducibility of paraspinal thermography using an infrared scanner. MATERIALS AND METHODS The thermal functions of a commercially available infrared scanner (Insight Subluxation Station®) were evaluated for clinical reliability. Two practicing clinicians conducted the measures on 100 subjects. Intra ...

objectives: to compare the outcomes of prone and supine lumbar traction in patients with chronic discogenic low back pain. methods: the test was prospective and randomized control trial. the structure of trial was urban physical medicine and rehabilitation clinic. participants was included of a total of 124 subjects with chronic low back pain (lbp) and evidence of a degenerative and/or herniate...

Plain radiographic assessment of primary total hip arthroplasty following surgery remains to be the commonest radiological assessment. The current paper, studies accuracy and concordance between observers reviewing these radiographs. A prospective medical note review ten patients who underwent replacement for osteoarthritis, with a mean age 69 years. Early 6 weeks postoperative x-rays were asse...

Deep multi-task learning attracts much attention in recent years as it achieves good performance many applications. Feature is important to deep for sharing common information among tasks. In this paper, we propose a Hierarchical Graph Neural Network (HGNN) learn augmented features learning. The HGNN consists of two-level graph neural networks. the low level, an intra-task network responsible p...
